Clouds & Stars It took a Colorado mom who was also a geochemist and environmental consultant to invent something completely different for her little one's crib. It was 2002 when she tried, for the first time, to change a crib sheet and quickly decided there had to be a better way. Today the privately held QuickZip® Sheet Company offers the only innovation to the fitted sheet since 1959, a line of baby bedding products designed to make your life easier. If you've wrestled with fitted sheets in a crib, loft, bunk bed, bed with rails or a bed placed in a corner or against the wall, you know it can be a real problem, especially for the elderly or those with arthritis. QuickZip® sheets are a patented two piece fitted sheet with a stay–put zipper base and a zipper "top" sheet that zips off and on for easy changing. Products include the Clouds & Stars™ QuickZip® zipper base and zipper crib sheet sets along with 100% cotton replacement crib sheets; the pastel sheets fit most standard crib mattresses.
